Indonesia Has Removed Its Rp50 Share-Price Floor. Can It Make the Market Work Better?

An investor can own a share marked at Rp50 and still be unable to sell it for Rp50. When willing buyers value the share below an exchange’s permitted minimum, the quoted price offers little comfort: sell orders can accumulate without finding a buyer.

Hitting the floor does not itself stop trading. A sell order can execute if a buyer bids at the permitted price; otherwise it waits, with earlier same-price limit orders taking priority. A broker can also seek a counterparty in the separately operated negotiated market. Neither route guarantees a buyer. IDX’s order-matching and negotiated-market rules

That is the economic problem behind the Indonesia Stock Exchange’s decision to lower the minimum price in its regular and cash markets from Rp50 to Rp1, effective September 28. The exchange says the change should improve price discovery, liquidity and investors’ ability to manage portfolios. It also adjusted daily order-rejection limits. ANTARA’s report of the implementation announcement

The reform can make a market function better even while some shareholders suffer falling prices. It permits transactions at levels previously unavailable in those markets. It does not increase the profits, assets or cash flows supporting a share’s value.

There is also a deeper question. If a controlling shareholder can retain board influence despite a collapsing public valuation, how much will a more informative price change corporate behaviour?

The historical evidence supports a qualified answer: removing a binding floor can facilitate trading; reverse splits can improve some aspects of liquidity; and neither measure, on its own, resolves weak businesses or conflicts between controlling owners and outside investors.

How large was the blockage?

Ajaib’s September 23 briefing reported approximately 48 shares at Rp50 as of August 27, with only 14 recording transaction activity. Separately, it counted 67 shares closing below Rp50 on September 4, before the new regular-market rule. These are snapshots from different dates and trading circumstances, not an up-to-date census of companies newly affected by the reform. They should not be combined into one affected-company total. Ajaib’s dated stock lists

The distinction matters because sub-Rp50 trading already existed. A share on a special trading board, a suspended security with a stale last price, and an actively traded regular-market share face different constraints. A lower floor does not automatically lift a suspension or attract bids to a company nobody wants to own.

GoTo provides a particularly clear example of the consequences of being stuck. On August 12, MSCI announced that it would delete the company from the MSCI Indonesia Investable Market Index using its lowest system price, 0.00001 in the security’s price currency. MSCI attributed the treatment to potential index-replication problems arising from very low liquidity while GoTo had traded at the Rp50 minimum since the close of May 13. That was an index-accounting treatment, not an executable stock-market price or a valuation of the business. MSCI’s GoTo announcement

This is evidence that the old floor could interfere with investability. It is not evidence that removing it will restore index membership or produce positive returns.

A lower price can help sellers—and make each price step larger

Consider a hypothetical share for which buyers are willing to pay Rp30 while the exchange permits no sale below Rp50. Allowing Rp30 creates the possibility of a trade. The seller receives less than the previous displayed price, but gains an exit that may previously have been unavailable.

That initial repricing must be separated from longer-term liquidity. A burst of transactions as trapped holders leave is different from a durable market with competing buyers, meaningful order-book depth and modest execution costs.

Indonesia’s price increments create another complication. IDX specifies a Rp1 tick for shares priced below Rp200. A fixed rupiah increment becomes proportionately larger as the stock price falls. The following figures are arithmetic, not observed trading costs. IDX’s trading-unit and price-fraction rules

A move from Rp1 to Rp2 doubles a share’s price; the reverse move halves it. These percentages describe the price grid, not a guarantee that an order will execute. Daily trading limits are a separate constraint, and prices still cannot fall below Rp1.

The policy therefore removes one obstacle while leaving a coarse pricing grid at the bottom. Successful price discovery may coexist with wide percentage spreads, shallow demand and considerable volatility.

What history can—and cannot—tell us

Singapore offers a useful comparison, although its former minimum-price rule was a continued-listing condition rather than Indonesia’s prohibition on regular-market trades below a floor. SGX introduced a S$0.20 minimum-price framework in 2015, with compliance beginning after a transition period in 2016. It explicitly encouraged share consolidations and waived related fees for two years. SGX’s 2015 announcement

In June 2020, Singapore removed that framework. SGX RegCo said it had been an imprecise instrument against manipulation: most companies on its minimum-price watch list had not been found to be manipulated, yet faced delisting risk and difficulties with bank borrowing and business relationships. The exchange strengthened other surveillance and financial-watch-list measures instead. SGX’s 2020 removal announcement

The lesson is limited but relevant. Enforcing a higher nominal share price did not prove a sufficient proxy for market quality. Singapore’s experience does not establish that abolishing Indonesia’s trading floor will raise its stock index; the policies differ, and a simple before-and-after comparison around 2020 would also be overwhelmed by the pandemic.

Research on reverse splits provides a different test. A 1995 study by Ki C. Han found narrower bid–ask spreads, higher trading volume and fewer non-trading days following consolidations, with no comparable changes in its control group. That supports the proposition that changing a share’s denomination can improve tradability. Han, Journal of Financial and Quantitative Analysis

Nasdaq’s 2021 analysis likewise found generally improved traded value, shorter queues, tighter spreads and lower volatility. But its main sample was deliberately restricted to 53 stocks priced above US$2 before consolidating, intended to focus on voluntary actions. That is a material difference from distressed companies pressed against Indonesia’s minimum. Nasdaq also reported a slight decline in median market capitalisation: better trading conditions and weaker valuations can occur together. Nasdaq’s reverse-split analysis

Indonesia’s own experience cautions against assuming that a reform’s liquidity objective will be achieved. A 2025 study of the 2024 Full Call Auction mechanism, focused on financial-sector stocks on the Special Monitoring Board, found statistically insignificant overall treatment effects. Some longer-exposed groups nevertheless showed wider spreads and persistent reductions in volume. The study concerns an auction mechanism and selected securities; it does not isolate the effect of lowering the price floor. Teto and Husodo, Universitas Indonesia

Together, these cases offer evidence about mechanisms, not a reliable numerical forecast for Indonesia’s September reform. There is no basis here for claiming that a lower floor adds a particular percentage to market returns or liquidity.

Why not require reverse stock splits?

A reverse split consolidates existing shares. In a hypothetical ten-for-one consolidation, an investor’s 1,000 shares quoted at Rp50 become 100 shares at a theoretical Rp500. The position remains worth Rp50,000 before any market repricing. A simple proportional consolidation does not raise cash or dilute the investor’s percentage ownership.

It can, however, help overcome a binding minimum. If those old shares would really have cleared at Rp30, the economically equivalent price after consolidation would be Rp300—comfortably above the former Rp50 floor. Depending on the applicable tick band, consolidation can also make the minimum increment smaller relative to the share price.

So the reverse-split alternative is economically credible. But it requires company-level action. Indonesia’s POJK 15/2022 requires shareholder approval and, for listed companies, prior in-principle exchange approval. Certain long-suspended or persistently floor-bound shares require a valuation report. Companies must also arrange a buyer for holdings left below the exchange’s trading unit by consolidation. These are real procedural requirements, not a simple change to a ticker display. OJK’s stock-split and consolidation regulation, Articles 3, 5, 10 and 15

Some companies have already taken that route. NETV’s October 2024 disclosure scheduled a two-for-one reverse split, with trading in the consolidated shares beginning on October 22 and a separate odd-lot purchase arrangement. Yet Ajaib listed NETV at Rp50 in its September 22, 2026 snapshot. Other financing and business developments prevent treating this as a controlled experiment, but the example demonstrates that consolidation does not guarantee a lasting escape from a low share price. NETV’s corporate-action disclosure, Ajaib’s snapshot

An exchange-wide reduction can give investors additional trading prices without waiting for each issuer to complete a corporate action. Reverse splits remain a possible complement, particularly where the price increment has become unwieldy. Neither approach creates a business turnaround.

Who feels the pressure when the share price falls?

InsideASEAN’s earlier analysis of family conglomerates, free float and MSCI examined the wider ownership problem. The Rp1 reform raises a narrower question: whether allowing a share price to fall further increases the pressure on those who run the company.

Family ownership enters the story through voting power, economic exposure and the supply of shares available to outside investors. Those dimensions must be separated. A family-controlled company can have substantial public trading, while a company controlled by the state or another corporation can have a tightly held float.

Indonesia’s governance structure distinguishes the executive board of directors from the supervisory board of commissioners. Shareholder meetings appoint board members. The practical implication is that a stable controlling voting bloc can exert much more influence over appointments than a dispersed public minority. Legal duties and minority protections still apply. OJK’s Indonesian Corporate Governance Manual

In a simplified company with one vote per share, a family holding 60% retains that majority whether the stock trades at Rp50 or Rp5. A falling quotation does not transfer its votes to dissatisfied investors. On ordinary resolutions where that majority is sufficient, the other 40% cannot outvote it while it remains united. Special voting thresholds and independent-shareholder requirements can alter particular decisions.

This creates a plausible separation between public dissatisfaction and board job security. It does not mean the controlling family is indifferent to losses. A substantial direct shareholder loses wealth too. A weaker share price can make new equity funding more dilutive, reduce the value of shares pledged as collateral where such pledges exist, and make acquisitions paid for in shares more expensive in ownership terms.

The balance depends on the company. A controller expecting to raise equity, sell shares or refinance share-backed borrowing has strong reasons to care about the quotation. A controller with little need for public capital and secure voting control may face less immediate pressure to respond. These are incentive mechanisms, not established motives of any particular Rp50 issuer.

Ownership chains can further separate control from economic exposure. As an illustration, a family owning 51% of a holding company that owns 51% of an operating company has a 26.01% indirect economic interest through that chain, while potentially controlling both companies. The actual voting arrangements must be examined; the illustration is not a claim about a named Indonesian group.

A major historical study helps explain why that distinction matters. Claessens and co-authors examined 1,301 listed corporations in eight East Asian economies. Firm value rose with the largest shareholder’s cash-flow ownership, but fell when its control rights exceeded its economic stake. The findings support both the benefits of owners having money at risk and the potential costs of entrenched control. Claessens et al., Journal of Finance, 2002

The Indonesian family-firm evidence is mixed

A study covering 147 Indonesian family companies during 2009–2014 found lower performance, measured by Tobin’s Q, than among non-family companies. It also found a non-linear relationship with family ownership and differences between founder and second-generation leadership. Tobin’s Q is a valuation measure; these results should not be presented as a percentage loss in shareholder returns. Septiana, Dalimunthe and Wasilah

A contrasting study of 120 family firms, comprising 600 observations over 2016–2020, reported positive performance associations with family presence, professional president directors and founder management. Its sample and measures differ, so the findings cannot simply be averaged into a single “family discount.” Study of family involvement in Indonesian companies

More recent published research using 2014–2020 data found that family ownership weakened the positive relationship between governance practices and market valuation, but did not significantly moderate the relationship with accounting performance. Another Indonesian study, using 2010–2014 data, found analyst following associated with better liquidity, while ownership structure itself had no statistically significant liquidity effect. Nasir et al., 2024, Shafiyyah and Utama

These are observational studies with different samples, periods and ownership definitions. They justify examining controlling-owner incentives. They do not establish that family ownership caused the current concentration of Rp50 stocks, or quantify how much of Indonesia’s market performance it explains. A company-by-company ownership analysis of the affected cohort has not been established for this article.

The policy implication is nevertheless clear: a more informative market price cannot by itself ensure that boards respond to minority shareholders. The relevant questions concern who controls votes, who bears economic losses, how related-party transactions are scrutinised and whether outside investors can influence capital allocation.

Indonesia is already addressing some of those issues separately. An April joint statement by OJK, IDX and KSEI described public disclosure of ownership above 1%, a high-shareholding-concentration framework, more detailed investor classifications and a phased increase in the minimum free float to 15%. The amended listing rule took effect on March 31 with transition arrangements for existing issuers; that does not mean every company immediately had a 15% float. OJK’s April reform statement

Those reforms tackle ownership transparency and available supply more directly than changing a nominal price floor. Their effectiveness depends on implementation and on whether disclosed public holdings represent shares genuinely available to trade.

How to judge the Rp1 reform

With only the first trading week elapsed by this article’s research cut-off, a durable verdict would be premature. The appropriate test follows the affected shares over several months, separates suspended and special-board securities, and compares them with otherwise similar shares that were not constrained by the former floor.

Raw share volume alone would be misleading. The same amount of money buys five times as many shares at Rp10 as at Rp50. A wave of selling can raise turnover while investors experience worse execution prices. A newly moving price can appear more volatile than a stale quotation without implying that the underlying business suddenly became more volatile.

The strongest case for the Rp1 floor is that investors should be able to discover—and, where buyers exist, transact at—prices the old rule prevented. The stronger test of Indonesia’s market will come afterwards: whether trading becomes consistently usable, and whether companies give outside shareholders reasons to keep owning them.
